The government's plan for tackling the UK's air pollution crisis has been judged illegally poor at the high court, marking the second time in 18 months that ministers have lost in court on the issue.
The defeat is a humiliation for ministers who by law must cut the illegal levels of nitrogen dioxide suffered by dozens of towns and cities in the "shortest possible time".
Legal NGO ClientEarth , which brought the case, argued that current plans ignore many measures that could help achieve this, placing too much weight on costs. On Wednesday Mr Justice Garnham agreed. He also said ministers knew that over-optimistic pollution modelling was being used, based on flawed lab tests of diesel vehicles rather than actual emissions on the road.
